Compact USB 3.0 card reader for SD and microSD

The Transcend TS-RDF5K is an external flash reader with two slots that accept SDHC, SDXC, microSDHC and microSDXC cards. It connects through a SuperSpeed USB 3.0 interface while remaining compatible with USB 2.0 ports. Photographers and videographers who need quick off-loading of high-resolution files will find it fits directly into a desktop or notebook without extra cables.

USB 3.0 bandwidth and UHS-I card limits

The reader uses a USB 3.0 connection that also works on USB 2.0, so transfer speed is bounded by the port you plug into. Cards are supported up to the UHS-I specification, meaning the hardware cannot utilise the higher bus speeds of UHS-II or UHS-III media. Users with those faster cards will see performance capped at the UHS-I level regardless of the card rating.

Ultra-compact build with LED activity light

The housing is small enough to stay plugged into a laptop during travel and draws power solely from the USB port. A built-in LED shows when a card is seated and when data is moving, reducing the chance of accidental removal mid-transfer. The two-slot layout covers both full-size and micro formats without an adapter, keeping the workflow simple for mixed card sets.
